on the 2004 GP GTP how do they achieve the 20 extra horsepower?? did they like port an M90 or something? also, has this 20 extra HP ever been proven on a dyno compared with the 97' - 03' GP's??
The supercharger i believe is ported a little bigger, and the intake valve is .02 larger...thats what they've found so far. Search for that thread on clubgp forums
if anyone is interested, Ed Morad has multiple BRAND NEW L32 motors, and will sell any parts off of them, trannys for around 1200-1400, blocks for around 800, gen V M90's, ANY part off an L32 motor, even pullies
Whcih parts are forged in those? Just the crank? I'd be interested in some durable parts like that eventually. As long as they hooked up easily that is
